Hinge



NITED STATES A JOHN C. MASON, OF NEW HARTFORD CENTER, CONNECTICUT.

HINGE.

To all whom it may concern:

Be it known that I, JNO. C. MASON, of New Hartford Center, Connecticut, have invented certain new and useful Improvements in Loose-Joint Butt-Hinges; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to t-he letters of reference marked thereon.

The nature of my invention consists in so constructing butt hinges that they may be made' a loose or solid hinge according t-o which side is attached to the door or casing as will be hereinafter described.

In order that others skilled in the arts may use and construct my invention I will proceed to describe its operation and construction.

In the accompanying drawings which make a part of this specification Figure 1 represents a door with my hinge attached forming a solid hinge. Fig. 2 represents a door withmy hinges secured to both sides of the door, the joint being loose and the door opening at either side. Fig. 3 is a view of one portion of the hinge, and Figs. 4, 5, and 6, are different views of the other portion of the hinge.

In Figs. l and 2, A represents the casing and B represents the doors, e being the bolts attached to each door c, and Z represent the .two parts of the hinge (el) is that part shown in Fig. 3 and marked (d) (c) is the part shown in Figs. 4, 5 and 6 marked c, 0", 0. The hinge is so constructed that when that part o, is secured to the casing and the part d, is secured to the door, as seen in Fig. l, it becomes a solid hinge, but when the parts are reversed as seen in Fig. 2, c, being secured to the door and d, to the casing it becomes a loose joint and the door will open either right or left with equal facility.

In putting this hinge together I take the part el, Fig. 3, and place it upon the piece 0', Fig. 6, both occupying the relative positions seen in the drawings, and being parallel to each other, I then slide the male portion, d, until it enters the female portion 0. It is then a loose joint hinge but as soon as the outer parts of each are moved out of parallel, the two parts are secured together and become a firm, solid hinge. The form of the under edge of the semicircular piece D, of Figs. 5 and 6 is shownv in Fig. 5 and represented by the letters z' and Fig. 3 is made to correspond in form to Fig. 5, o, of Fig. 3, passing singly under z', of Fig. 5, and p, of Fig. 3 passing snugly under zo of Fig. 5.

The particular advantage of this hinge is that it is cast without the use o-f a core and is put together without drilling. It is perfectly plain casting and is much cheaper lthan any other cast hinge now known as .manner that one portion of it being secured to the door or window it becomes a solid hinge and opens only one way, while the other being secured to bot-h sides, the door or window will open at either side. This hinge is also applicable to gates or anything which operates upon hinges.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is- I claim the construction of a loose joint butt hinge which becomes a tight joint as soon as turned from the position in which it is put together in the manner herein set forth, or in any other manner substantially the same, whereby I am enabled by putting hinges on each edge of a door, to open it right or left, or by reversing the butt, to make a solid hinge, as herein described.
